A facial allotransplanted patient presented hyperglycemia with blood glucose ranged 14. 3 -33. 3 mmol/L after receiving immunosuppressive drugs and glucocorticoids. To control the blood glucose level, the patient was treated with two subcutaneous doses of 10 U human neutral protamine hagedorn (NPH) insulin, and the fasting glucose level came down to 3. 6 - 9. 4 mmol/L. Then the continuous subcutaneous infusion of insulin aspart ( Novo Industri) was administrated (from 96 to 21 U/d) , and the fasting blood glucose levels were 3. 9 -4. 6 mmol/L. With oral administration of Metformin and Repaglinide, the fasting blood glucose was maintained to 4. 3 -5.9 mmol/L. With these medications, the blood glucose level of the patient was under good control and the acute and chronic complications of hyperglycemia were effectively prevented.

Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.

OBJECTIVETo study the potential aging effect on workers exposed to acrylonitrile (ACN).

METHODSThe deletion rates of mitochondrial DNA (mtDNA) in peripheral blood nucleate cells of 47 exposed workers and 47 non-exposed workers (as control), as well as 12 old people and 12 young people were measured with polymerase chain reaction (PCR).

RESULTSThe positive rates of mtDNA deletion in peripheral blood nucleate cells were 17.02% in the workers exposed to ACN and 25.00% in group of old people. However, the mtDNA deletion was not detected in the control group and young people.

CONCLUSIONSACN could induce mtDNA deletion in peripheral blood nucleate cells of the exposed workers. There may be a potential molecular effect of occupational ACN exposure on workers' aging.

ObjectiveTo investigate the protective effects and its mechanism of ischemia postconditioning (IPO) in hepatic ischemia-reperfusion injury (IRI) in liver cirrhotic rats.MethodsThirty liver cirrhotic Sprague-Dawley (SD) rats were randomly divided into three groups according to the random table methods: ischemia postconditioning (IPO) group, IRI group, and pure hepatectomy (PH) group with 10 rats in each group. Rats in IPO group underwent partial hepatectomy (40%), and the first portal was occluded for 20 min, then 3 times of ischemia-reperfusion were performed, and ifnally continuous reperfusion. Rats in IRI group underwent partial hepatectomy (40%), and the ifrst portal was occluded for 20 min, then continuous reperfusion was performed. Rats in PH group underwent partial hepatectomy (40%) only. Inferior vena cava blood was collected at 6, 24 h after operation. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), proportion of cluster of differentiation (CD) 4+, CD8+, regulatory T cells (Treg) and levels of interleukin (IL)-4, IL-10 were tested. Comparison of three groups was conducted by one way analysis of variance and pairwise comparison by LSD-t test.ResultsAfter 6 h reperfusion, levels of ALT and AST in IPO group [(1 623±378) , (1 993±469) U/L] were signiifcantly lower than those in IRI group [(2 690±549) , (3 020±577) U/L] (LSD-t=-4.21,-3.72; P<0.05). After 24 h reperfusion, levels of ALT and AST in IPO group [(307±76) , (555±137) U/L] were still signiifcantly lower than those in IRI group [(518±105) , (1 050±355) U/L] (LSD-t=-4.06,-3.37;P<0.05). After 6 h reperfusion, proportion of CD4+, CD8+, CD4+/CD8+ ratio, Treg, and levels of IL-4, IL-10 in IPO group were (57±5) %, (25±3) %, 2.3±0.5, (8.9±0.4) %, (1.27±0.25) mg/L, (0.61±0.03) mg/L, respectively. While in IRI group, they were (52±6)%, (12±3) %, 4.5±0.8, (7.3±0.3) %, (0.66±0.11) mg/L, (0.34±0.06) mg/L, respectively. In IPO group, CD8+, Treg, IL-4 and IL-10 increased signiifcantly, while CD4+/CD8+ ratio decreased signiifcantly, compared with those in IRI group (LSD-t= 7.74, 6.67, 5.52, 9.31,-6.69;P<0.05).ConclusionIPO can prevent from hepatic IRI injury in liver cirrhotic rats through decreasing the immune injury.

OBJECTIVETo explore the etiology of idiopathic talipes equinovarus (ITEV) in all-trans retinoic acid (ATRA) induced clubfoot-like deformity in rat fetuses with two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS).

METHODSClubfoot-like deformity model in rat fetuses was induced with ATRA (135 mg/kg) in gestation day (GD10) pregnant Wistar rats. 2-DE was applied to separate the total proteins of ankle joint tissue, ankle joint bone and spinal cord of the animal models. The Coomassie Brilliant Blue staining gels were analyzed by 2-DE software PDQuest 7.1.0. Selected differential protein spots were identified with peptide mass fingerprinting based on matrix-assisted laser adsorption/ionization time-of-flight mass spectrometry and database searching. xiap, tnnt1 and col2 alpha 1, three genes of the differential proteins, were identified furthermore. Apoptosis study was made in terminal deoxynucleotidyl transferase nick end labeling.

RESULTSThere were many differential expressed proteins in the clubfoot-like deformity model. Out of the differentially expressed proteins,16 protein spots were identified to be differentially expressed in the clubfoot-like deformity model with MS. Three of the 16 protein spots, xiap, tnnt1 and col2 alpha 1 were confirmed to be significantly down-regulated by the RT-PCR, and Xiap was further confirmed to be significantly down-regulated with immunohistochemistry. Another randomly selected gene, ngfr, did not express differently in ATRA-induced clubfoot-like deformity in rat fetuses. The rates of the apoptosis in the spinal, bone of the clubfoot-like deformity fetuses was 5.4 and 10 times of those of the normal fetuses respectively.

CONCLUSIONThe results suggest that there are certain differently expressed proteins in ankle joint tissue, ankle joint bone and spinal cord of the ATRA-induced clubfoot-like deformity in rat fetuses, and Xiap, sTnT, and Col2 alpha 1 show a significant correlation with ITEV. Ngfr is not correlation with ITEV. Apoptosis plays a key role in the development of ITEV and related to the decreased expression of the Xiap.

Objective On July 6, 2010, the parents of a patient with confirmed measles reported several suspected measles patients with fever and rash in their village. An investigation was carried out to verify and understand the cause of the outbreak. Methods Several suspected cases had an onset of fever and rash in this and other neighboring villages during June 1 to August 3,2010. A confirmed case was a suspected case with measles-specific IgM identified in the serum. We conducted door-to-door visits and searched the Chinese Center for Disease Control and Prevention Information System to identify cases, also conducted a retrospective cohort study among migrant children aged 8 months-14 years to identify risk factors related to measles. Results We identified 19 measles cases (17 confirmed case, 2 suspected cases)in the village, and all of them were migrants. Children aged 1-2 years had the highest attack rate(13%). The primary case-patient had onset on the day she arrived in this village(June 4,2010). Caretakers from an unlicensed private clinic were providing service in the village but did not report the outbreak to the public health authority. The outbreak was identified only after receiving a report from the parents of one of the patients, by that time the outbreak had lasted for one month. The measles vaccine coverage rate was 81% among the 315 migrant children aged 8 months-14 years. Among the 61 unvaccinated children, those who reportedly being contacted a measles patient had a higher attack rate(14/16, 88%)than those who did not(2/45, 4.4%)(Relative risk=20, Fisher' s exact 95% confidence interval: 5.7-94). Conclusion The low measles vaccine coverage among migrant children and lack of measures taken on the incident, timely isolation diagnosis/reporting by the caretakers from the unlicensed private clinic etc. had contributed to this prolonged outbreak. Measures need to be taken to improve the immunization services for migrant populations and to enhance measles surveillance programs in the area.

OBJECTIVETo investigate the relative quantification of cytokeratin 19 transcription in oral squamous cell carcinoma tissues by fluorescent quantitive real-time reverse transcription-polymerase chain reaction ((RT-PCR).

METHODSCK19mRNA level was detected by fluorescent quantitive real-time RT-PCR in cancerous and para-cancerous tissues from 31 oral squamous cell carcinoma patients. According to the 2(-DeltaDeltaCt) equation, the relative quantification fold of CK19mRNA level was calculated in cancerous tissues compared with para-cancerous tissues.

RESULTSCK19mRNA levels in cancerous tissues were 2.21 folds higher than those in para-cancerous tissues, and the amplicon was specific. CK19mRNA level in cancerous tissue correlated significantly with pathological differentiation degree, the poorer the differentiation was, the higher the CK19mRNA level became.

CONCLUSIONSFluorescent quantitive real-time RT-PCR is accurate and reliable in the detection of relative quantification of CK19 transcription in oral squamous cell carcinoma tissues.

Conclusion Endoscopic papillectomy is an effective method for treating tumors of major duodenal papilla.

OBJECTIVETo explore the mechanism of tanshinol on alleviate the inflammatory injury of lung tissue in rat hepatopulmonary syndrome (HPS).

METHODSSD rats were randomly divided into normal control group (n = 8), hepatopulmonary syndrome (HPS) group (n = 11) and tanshinol intervention group (n = 9). HE staining was used to observe the histopathology changes of pulmonary and hepatic tissues, and to count the number of macrophages in lung tissues. The activity of alanine transferase (ALT) and concentrations of endotoxin, tumor necrosis factor-a (TNF-alpha) and homocystein (Hcy) in plasma were detected. The concentrations of TNF-alpha, nitric oxide (NO) and malondialdehyde (MDA) and the activity of inducible nitric oxide synthase (iNOS) in the lung tissues were measured, respectively.

RESULTSThickened alveolar septum and increased macrophages were observed in lungs in HPS rat. After administered with tanshinol, the pulmonary pathological changes were alleviated and the number of macrophages in lung tissue was decreased compared with HPS group. The activity of ALT and the concentrations of endotoxin, TNF-alpha and Hcy in plasma ,and TNF-alpha, iNOS, NO and MDA in lung tissue in HPS group were higher than those of normal control group; meanwhile, those tanshinol group were less those that of HPS group.

CONCLUSIONTanshinol may play an important role in delaying the development of HPS through protecting liver or directly antagonizing the effect of intestinal endotoxemia so as to alleviate the inflammatory reaction in lung tissue.
